Major process system failures and subsequent poor diagnosis continues to produce significant company disruption, environmental damage, injury and possible loss of life. The benefits of this work will be reduced impacts and risks. This work will provide a new integrated approach with structured tools and diagnostic designs for process industries. It should have direct impacts on company performance through improved diagnosis, more timely response and hence reduced likelihood of major accidents. It will help to improve overall risk management practice in the process industries with less impact on people, property and environment, thus improving operational performance. Local communities will be direct beneficiaries of these reduced risks.Read moreRead less
Optimising Fouling Control in Membrane Bioreactors. Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs.

Membrane bioreactors (MBR) are growing in importance for wastewater treatment because they offer an alternative for producing higher effluent quality wastewater within a more compact space compared to conventional processes. However, due to the pumping and bubbling used to keep the membranes clear of foulants resulting from the biological processes in MBR's, controlling fouling incurs significant energy usage and costs. The proposal aims to reduce the costs of fouling control by understanding the optimal conditions to remove these depositions and improve the design of MBR modules, operating conditions and shear delivery in the membrane system.Read moreRead less
Macromolecular Fouling in Membrane Bioreactors. As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes.

As the demands for domestic and industrial water increasing in Australia and overseas, membrane bioreactors (MBR) offer an alternative for producing higher effluent quality wastewater compared to conventional processes. However, aeration costs used to remove fouling deposits (which reduce the operating performance) need to be further minimised. The proposal aims to study fundamental mechanisms involve in the deposition of foulant components by using model systems of polysaccharides, proteins and microbial cells and comparing these with real MBR systems. The effect of bubbling varied gas compositions (air/H2S ratios) a novel approach in this study will be investigated to prevent or remove foulants in MBR systems. Read moreRead less

Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this info ....Wet granule mechanics and their influence on agglomeration behaviour and granulation processes. Granulation is a widely-used particle size enlargement process performed by spraying a liquid binder onto an agitated powder mass. It is currently impossible to quantitatively predict granule growth behaviour in terms of the fundamental properties of the particles and binder. This project will measure and model the deformation of granules and the strength of bonds formed between them and use this information to predict their growth behaviour. Special attention will be given to the effects of strain-rate and particle morphology in granulation mechanics. Improvements in granulation technology will be of great benefit to food, pharmaceutical, agricultural, explosives and mining industries and opens the way to 'designer granulation' for special purposes.Read moreRead less

Frictional and viscous effects during transport in nanopores. Gas mixtures exposed to materials containing molecular sized pores (nanopores) are adsorbed, forming states of matter not existing in the bulk. Differential forces acting on the components of mixtures promote industrially and environmentally important separations. However, transport of confined fluids has been poorly understood. Recently we have made progress using computer simulation, and have proposed a highly successful theory. ....Frictional and viscous effects during transport in nanopores. Gas mixtures exposed to materials containing molecular sized pores (nanopores) are adsorbed, forming states of matter not existing in the bulk. Differential forces acting on the components of mixtures promote industrially and environmentally important separations. However, transport of confined fluids has been poorly understood. Recently we have made progress using computer simulation, and have proposed a highly successful theory. These investigations have revealed the crucial role of scattering from the surface atoms of the confining solid. Theoretical investigation of single spherical species has been initiated, and extension to other species and to mixtures is now envisaged.Read moreRead less

Good understanding of transport mechanisms in nanopores is crucial to the successful application of numerous recently developed novel templated microporous and mesoporous materials. This project seeks to extend a new theory developed by the applicants for single component transport in cylindrical mesopores, to cylindrical micropores as well as to multicomponent adsorbates, in conjunction with experiments using microporous and mesoporous materials such as MCM-41, VPI-5 and AlPO4-5. The outcome will be a powerful new theory for a priori prediction of transport coefficients for multicomponent fluids in nanopores based on molecular level information alone, thereby overcoming the empiricism in existing models.Read moreRead less
